To all wiwm 'it may concern:

Be it known that l. IIARBY B. Hun-1mm, a citizen of the United States, residing at Juliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in 'iredtawingllltrks. of which the following is a specification.

It is the practice, in the drawing of wire, to employ grippers for grasping the wire as it: leaves the drawing die. and carrying the advance end of the drawn wire into post: tion to be wound or coiled on the block; Ind it is likewise the custom to employ a block having a rising and falling movement, for the falling movement to connect the block with the revolving shaft. so as to revolve the block, and for the rising movement to disconnect the block from the shaft. and allow the shaft to revolve without revolving the block. The practice heretofore has been to employ grippers connected with the block asping t 0 end of the wire for drawe wire onto the block as the block is revolved; and to operate the block by means 'of a kick lever and connections, so that in the falling of the block more or less concussion or jar will occur as the block is an ht and revolved.

e objec s of the present invention are to construct and operate a gri per in direct connection with the blm'li, so t nit as the end of the wire is caught by the gripper. it, with the ripper, will he carried (liItX'llIi' onto the ravo ving block: to furnish a flexible connection lxetween the gripper and the block, for enabling the grip m! to be lowered to cltch and hold the en of the wire: to furnish an automatic means for gradually raising the gripper as the wire asrends or passes it ward on the block: to construct a revolnbe block and a gripper coacting to wind or reel the wire on the block; to gradually and positively connect the block with thc rcvolving shaft, so as to prevent jar and cow cuasion'to any appreciable or injuriousextent in starting the block: to construct and apply a friction clutch formc-l of several tedious and operated to engage the block as the block descends. and to he discngagcd ply a friction clutch consisting of scvcral Sections. each section operated h v links for,

of the supporting frame; Fi 2 a side ele-v vation of the supporting bloc and its driving shaft and gear, withthe frame in section: Fig. 3 a sectional plan view of the block. showing the arrangement of the friction clutch; F ig. 4 a top or plan view of a block. showing the connection of the gripper with the block; Fig. 5 a sectional elevation. shuwin the block raised and the friction clutch isengaged; Fig. 6 a similar view to. Fig. 5, showing the block lowered and thefriction clutch engaged: Fig. 7 a sectional plan view of a'gripper; Fig. 8 a longitudinul central section of a gripper; Fig. 9 an end or face view of a gripper: and Fig. 10 a perspective view of one of the gripper aws.

The block of the present invention has a "central section or portion 1, a lower flange or rim 2. an upper shoulder 3. and an upper flange or rim 4. with lugs 5 on the uppcr flange or rim having holes. for the reception of rods, to incrcasc the hcight of wind for the wire. cross plate 6 extcnds across the upper part of the block. and at the axial center is a hub T. furnishing a hearing for rewlving th block. A chain 8 is connected by an eye or loop 9. with a pin 10 cxtl'htlillg' up from the plate 6. and this chain passc-a through a slot or opening ll in the rim or flange 4. and its outer or free end is conncctcd with the are 1; of the gripper platc l3. which has sockets H. in the construction shown. that join each other at the front or rccciving end and form a nose 15. and each socket H has a passage or holc Hi. cach of which receives a grip x-r jaw 17, havinga serrated grimicr face 18: and each gripper jaw is held projected by a coilcd spring 19. which allows of thc nt'ccssar) rcarward uovcmcni for thc cntcring of thc cm] of the wire lmtwccn the scrratcd or toothed faces of thc jaws. The spring li is located hclwccn the rear end of each grippcr jaw and a closing plug 20. hcld in place h a cross pin 'l. or in any othcr suitable manner. Each grippcr jaw. at its from or receiving around by the revolution of the block.

end. has a countersink 22. and the center or web of the grtpper hlocl; or holder has a hole 23 for the passage of thc end of the wire a sufitcient distance beyond the grippingfaces of the jaws. so as to insure a firm bite on the wire, by which the wire will be drawn forward as the gripper jaw is carried The specific form of gripper shown and as scribed forms no part of the present invention, and will constitute the subject matter of a separate application.

- The gripper whether of the form shown. or other form, has a flexible connection with the. block by meansof the chain 8. and after the wire is caught and commences towind onto the block the gripper. as a whole. rises to be kept clear of the wire, and for this purpose. in the construction shown, a chain 2% is attached to the bye 1:3 of the gripper head or plate. and this chain 24 passes through a hole or opening '25 in the rim 3. and is attached to one end of a coil spring 26, which spring is locatednind operates in a casing 27, attached to the inner fire of the rim 3 by brackets or cars and.

derstood from the foregoing set screws 29, or in any other suitable manner. The spring 96. when the gripper as a whole is lowered to grip the end of thewire, is expanded by the act of pulling the gripper down to position to catch the end of the wire, .and with this downward movement the chain 24 passes down with the gripper. and after the gripper is attached to the wire and the block starts to revolve and wind the wire on the block, the spring 26 self-retracts. drawing back the chain 24 and raising the grip er 'radnally with the rise of the wire on t e block.

The operation of the grip er will he unescription. but. briefly is as follows: The wire is inserted between ;he jaws of the gripper. and withthe start of the rotation of the block. the gripper will be drawn toward the block, and the aws will be forcibly engaged with the wire, holding the wire firmly can and as the gripper passes around with the. rotation of the. block the. wire will follow and will be wound onto the block, and when the necessa amount of wire. has been wound or tea ed onto the block the gripper can be released, either b cutting the caught and of the wire or 0t erwise, leaving the reel of wire free to be removed from the block, and leavin the gripper in position on the block to cats 1 the forward end of the next section of wire and reel another portion of the wire onto the block.

It will be seen that with the gri per of suitable formation connected direct y with the block, only one grip is necessary on the pur block. all of the gripped portion of the wire must he cut oil and thrown away. The gripper is positive in its action. and will operate and catch the wire and carry the wire to the block with the revolving of the block.

The interior of the block has an annular chamber or recess 30. in which is located and o ieratcs the friction clutch. The frietion clutch of the present invention consists of six sections in the arrangement shown. but a greater or less number of sections could be used. if so desired. .l*1ach section of the friction clu ch consists of a shoe 3 of wood or other suitable material held in s supporting head each head 32 having ears between which cars is attached. by a pivot pin 34. one end of a link 35 and, as shown. a stop lug 36depends from the under face of the link to prevent the free end of the link from descending too far. The free end of each link 35 has a. slot or pa sage 37. in which is attached. by a pin or pivot 39. the upper end of an arm or link 31-). the lower end of which is attached by a pin or )ivot 40 between ears or plates 41 of the lab c or platform supporting the block. and the plates or cars ll have a curved upper face 42 over which a pin 43 rides to maintain the. proper throw of the arm or link in the operation of each shoe of the friction clutch. collar or ring 44. having it her eled under face is located above the series of links 3,). and this ring. on its upper face. has projecting pins 45. to which is connected a loop or eye 46 of a coiled spring 4?. the other end of which has a loop or eye 48 em tered onto the pivot or pin 34 or otherwise having a fixed point of attachment, so that the spring will act.- and maintain the proper relation between the shoe of each section and the links or arms which operate the shoe.

A conical hearing 49 furnishes a support for the free ends of the links and this hearing has a cross hole 50 in which is located a block or not 51, receiving the threadcd end of an adjusting rod so that. by turning the rod. the b ock with the conical bearing can be raised or lowered. for which so a slot 53 is formed in the driving sha and the rod 52 has its stem extending upwardly through a. hole 54 in the driving shaft, with a head 55 on the end of the stem. the head having a nick or other means which will enable the rod 52 to he turned in the not or.cross head 51 and properly adjust the cone as required to take up or compenend of the wire, so that only the short piece" sate for wear on the shoes of the friction of wire caught h need be cut on an thrown away, while with The shaft 56, in whichis the slot'53 and pa agr 54. has attarhed the-rein. by a key 57 or oihrr 'ise. a rollar 51% supportiing the bottom or driving plate .39 of the block; and. as hot-oi. thrdriving plate has a series. of stops on. ram attarhed thereto by a sr'rew 61 or otherwise. whit-h l)l(Xl(S are engaged by thr ands of the iiUt-ri. and serve to furnish a nllllf' ll ll for driving thev frirtion clutch. tor the fri tion rlutch. when the shoes are Pngaged with the iamof the block to rotate or drive the dock. The rim or flange 2. in the arrangement shown. rides on rollers 5?. in the slotted end of rod's or liars 63. and these bars are runner-ted each by a pin or pivot 1 with the slotted end 65 of each arm fit of a cradle. the arms of the cradle extending around a stop rnllar (9T. fixedly attached to the driving shaft .36 under the huh 57 by a set holt 654 or otherwise. Each arm i of the rradle at its slotted end 65 rarries a pin or pivot on. by means of which the rradle is pivotally mounted on the end of a hanger or support 70. and at the free end of the r'radle is an arm 71' having an eye 72. to which is ronnerted one end of a rod 73. the other end of which is connected to a kirk-01f lever 74 as usual. which lever, at its attached end. is mounted on a pin or pivot- 75 carried by an ear T6 or otherwise, and c0- operates with an upper stop T7 and a lower stop 78. as usual in the construction and arrangement of kirk-off levers. for raising and lowering a wire block.

The driving shaft 56 is driven by r: hevel gear 79, which meshes with a bevel gear 80. on a driving shaft 81 supported in suitable journal hoxvs or bearings 82 on cross plates or liars attached to the front and rear side pieres 8t of the main frame. and the sidr pier-es 8% are connected by uprights 85 with the upper pieces 86. on the front one of whirl is mounted the usual draw die 87, and. as shown. a protecting flange 88 is carried by the upper supporting frame pieces ML and rnrirrles the lower rim of the block to prwent the falling down of the drawn wirr HS wound on the i)l0(l(. as usual.

Tho operation of the clutch. to which this part of the invention partirularly relates. is as follows: The kirk-off lever. when in its !':|l t'tl position, will elevate the block through llw riigagmnent of the flange or Ii-ark 2. with h IHllfl'i H2. and thr raising of tlirroller; through the har 63. and the fllltlt'i' or rlidha. and with su n elevation of tho iiior'lt tluouter rml of the links 35 Will lK' drawn inwardly. .\'illlil!'n'\\ll'l;[ the shoes 31 from ngagenwnt with the inner fare of tho hlovlr. as shown in Fig. 5. allowing the "Rid" or platform 59. with llm FTQPS it). to

rmolvt'. rarrving around the sz-rtions of the ii'l lifill nlut h without imparting movement lathe lilorir. 'lhn dismigagrnwnt of the kirlc tl' lr-r r from the upprr stop 77. and llnr rngagvnwni'lhrztnf with tht. lower stop 78. CRITlQS down the block, and with the desrent of tho hlork the outer end of tho links 35 are turned outward. rousing the shoes 31. of the friction rlnteh, to impinge and firmly hind against the inner fare of 7. the hlork. so that. with the rotation of tinplatform or tahle .39. and the stops H0. the friction tllllt'll. in its engagement with the inner fave of the hlork. will revolve the block. The engagement of the friction 7.3 rluteh. with-the block. will he gradual. thew. by giving a gradual rotation to the block. so that no jar or i-onrussion will orrur in starting the revolution of the block. whirh is very desirahle in the operation of tho so hlork. and pavtit-ularly so where the gripper is connected with and drawn forward by tho block. as with a gradual increase of rotation of the block. no sudden draw or pull will he exerted on the wire. whirh would tend to 85 break ml the wire at the point naught by tlw gripper. The rono hearing-l9 enables the proper adjustnu-nt of the desrent of the block to he obtained. for taking up of wear in the use of the friction clutch. and the 90 springs serve to insuro an inward draw on the shoe by whit'h the shoes. when tho block is raised. are maintained out of rontart with the coarting su'rfaee of the block. The frietion clutch of the presentinvention is automatic' in its operation. and by its use a perfert ronnection' hetween the block and the driving platform or table is obtained. without the produrtion of jar or ronrussion that might cause injurious effects.

The gradual start of the wire block, by reason of tho gradual engagement of tho friction chm-h with the block. is very desirable in ronnertion with a wire gripper ha v ing a direct connortion with the wire hlork 305 as in the present invention. for tho reason that with a gradual start of the rotation of the block no sudden pull or strain will he plarrd on the raught wirr as would he tho case with a sudden .jerk in starting tho block. and the danger or liability of breaking tho wire with the initial start of\the I ipper is. redured to a minimum. tlu-rehy 1e uclng tho' amount of waste for the wire caught l) the gripp r. The. vXn-rior of the wire block. by its sontion 1. furnishes a fare onto which the wire winds rradily. and as the winlifl'fi andtho grippvr is antomatirall raisrd hy the notion of thrn nsion spring. the gripper is maintainml ont 'oi' contact or interferenre with tho winding of the wirr on the block, and when thr'face of lllt sertion l of the block is r-ntirely tillnd with thewire. and it is desired to increasethe amountof wire wound, tho blot-k. hv reasonof theupper invention enables the operator to make the i within the interior of the blockand inclosing younection between the block and the wire by a single grip on the wire, dispensing with the necessity of making several grips on the wire before the wire is brought to the old F construction of block to be caught thereon,

which results in a great saving of time in placing the wire on the block which, in connection with the reducing of the danger of breakage to a minimum. makes the wire block and gripper of the present invention exceedingly desirable and useful in wire drawing mechanism.
